Application of suture anastomosis in nasal endoscopic dacryocystorhinostomy / 中国内镜杂志

ABSTRACT

Objective To investigate the efficacy of endoscopic dacryocystorhinostomy(En-DCR)and suture anastomosis in treatment of chronic dacryocystitis.Method Clinical data of 79 cases(79 eyes)of chronic dacryocystitis were enrolled retrospectively and divided into suture group and seamless group.In the seamless group,the En-DCR valve was fixed with simple gelatin sponge,and in the suture group,the En-DCR valve suture was used.The total clinical effective rate,postoperative complication rate,anastomotic repair time and granulation hyperplasia of the two groups were analyzed and compared.Results There was no statistically significant difference in total effective rate between the two groups after operation(χ2 = 4.36,P = 0.137),there was no statistically significant difference in the incidence of complications(P = 0.705).The healing time of stoma mucosa epithelium in suture group was shorter than that in seamless group,the difference was statistically significant(t = 0.57,P = 0.032);The stoma granulation hyperplasia suture group was less than the seamless group,the difference was statistically significant(P = 0.037).Conclusion The combination of valve suture does not improve its clinical efficacy and safety,but can shorten the healing time of mucosal epithelium and reduce the granulation hyperplasia of stoma.
